Okay, I found it out. There is something wrong with the serverconfig. in fetch.php: if(($conf['gdlib']>1) && function_exists("imagecreatetruecolor")){ $newimg = @imagecreatetruecolor ($to_w, $to_h); } if(!$newimg) $newimg = @imagecreate($to_w, $to_h); if(!$newimg){ imagedestroy($image); return false; } The function_exists("imagecreatetruecolor")-request seems to be false, so only imagecreate is used. I tried to change the second if-clause to if(!$newimg) $newimg = @imagecreatetruecolor($to_w, $to_h); And now it works. Does anybody know about such a problem? But anyway, now it works.
